How to do cable one arm tricep pushdown
Master the setup, range of motion, and tempo for safer, more effective reps.
Overview
The one-arm tricep pushdown is a fundamental movement for building arm thickness and strength. By using a single arm, you can focus entirely on the 'mind-muscle connection,' ensuring that the triceps are doing the work rather than relying on momentum or the chest. The cable provides constant resistance, which is especially effective for the triceps, as they are most active during the final lockout of the arm.
Why Use It
- Provides constant tension throughout the entire range of motion.
- Allows for better isolation of the triceps by removing the ability to 'cheat'.
- Helps fix strength imbalances between the left and right arms.
When to Use It
This is an excellent accessory move for any upper body or arm-focused session. Use it after your heavy presses or dips to specifically target the triceps.
Instructions for Proper Form
Setup
- Pulley Height: Set the cable to the highest position. Attach a single handle.
- Stance: Face the machine with your feet hip-width apart.
- Grip: Grab the handle with an overhand grip and pull your elbow down to your side.
Execution
- The Extension: Push the handle down until your arm is completely straight.
Pro Tip: Imagine you are trying to push the handle through the floor.
- The Squeeze: Contract your triceps hard at the bottom for a full second.
- The Return: Slowly bring the handle back up toward your chest, stopping when your elbow wants to move forward.
Coaching Cues
- "Keep your elbow pinned to your ribs."
- "Only move your forearm."
- "Lock it out hard at the bottom."
Common Mistakes
- Elbow Flaring: Letting the elbow point out to the side, which brings in the chest and shoulders.
- Using Momentum: Rocking the body to help push the weight down.
- Partial Reps: Not going all the way down or all the way up.
How to Fix It
- Elbow Flaring: Imagine there is a pin going through your elbow into your side; keep it locked there.
- Using Momentum: Stand with your back against a wall or post to keep your torso perfectly still.
- Partial Reps: Focus on touching your forearm to your bicep at the top and fully locking the elbow at the bottom.
Mistakes by Level
Beginner
- Moving the shoulder instead of just the elbow
- Standing too far back
Intermediate
- Losing tension at the top
- Wrist curling at the bottom
Advanced
- Using too much weight and losing the squeeze

Form Checklist
- Is your elbow staying tucked in at your side?
- Are you getting a full lockout at the bottom?
- Is your torso staying still?
Range of Motion
From a fully bent elbow to a fully locked-out arm at the side.
Breathing Pattern
Exhale as you push the handle down; inhale as you control it back up.
Tempo Guidance
2-0-1-1: Two seconds up, no pause at the top, one second down, and a one second squeeze.
Caution Notes
- Avoid letting the elbow drift forward or backward during the rep.
Programming
Treat these guidelines as practical programming defaults, then scale load, volume, and frequency to match the rest of the training week.
Best For
- Triceps hypertrophy
- Improving lockout strength
- Arm definition
Goal Tags
Rep Ranges
- 10-12 reps for strength/size
- 12-15 reps for hypertrophy
Set Guidance
3-4 sets per arm
Rest Guidance
45-60 seconds
Frequency
2-3 times per week
Pairings
- Close Grip Bench Press
- Bicep Curls
Audience Notes
- Focus on the 'squeeze' at the bottom to maximize tricep engagement.
Substitution Targets
- Dumbbell Kickback
- Two-Arm Rope Pushdown
Variations
Use progressions to increase difficulty when you master the movement, and regressions if you struggle with proper form or face mobility limitations.
Regressions
Two-Arm Pushdown
Easier to stabilize and allows for more weight.
Best for: Absolute beginners.
Progressions
Reverse Grip Pushdown
Shifts the emphasis slightly to the medial head of the triceps.
Best for: Advanced arm development.
FAQ
Common Questions
Should I use a handle or a rope?
A handle allows for more weight and stability, while a rope allows for a slightly deeper contraction at the bottom.
